DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Specifies the port for transmission, and enters interface configuration
mode.
interface interface-id
Example:
Switch(config)# interface
Step 2
gigabitethernet 1/0/2
Selects the PAgP learning method.pagp learn-method physical-port
Step 3
Example:
Switch(config-if)# pagp learn-method
By default, aggregation-port learning is selected, which means the
switch sends packets to the source by using any of the ports in the
EtherChannel. With aggregate-port learning, it is not important on which
physical port the packet arrives.
physical port
Selects physical-port to connect with another switch that is a physical
learner. Make sure to configure the port-channel load-balance global
configuration command to src-mac.
The learning method must be configured the same at both ends of the
link.
Assigns a priority so that the selected port is chosen for packet
transmission.
pagp port-priority priority
Example:
Switch(config-if)# pagp port-priority
Step 4
For priority, the range is 0 to 255. The default is 128. The higher the
priority, the more likely that the port will be used for PAgP transmission.
